You can order O.1M (sometimes called 0.1N) silver nitrate (SN) and 0.1M sodium thiosulfate pentahydrate (STP) solutions from amazon. The silver nitrate breaks down in light, so keep it in a dark place.

Make a “stock solution” of 1 part SN to 4 parts STP (about 50mL should be enuff for one plant)...the stock solution has a short shelf life, so don’t make more than you need.

Mix the actual spray you use by diluting the stock solution with water between 1:5 and 1:9.

Soak the nodes with the spray every 5 days; flip lights after 1st week. Usually 4-5 sprays does the job, but you can spray as long as you want.

I haven’t used a surfactant/dishsoap.
 
What is your goal with the pollen? Are you making feminized seeds? Do you harvest and save the pollen or do you let them self pollinate?
